High-Sensitivity Compact Fiber-Optic Coherent Micro-Vibration
In this paper, a compact micro-vibration sensing system assisted with silicon photonic integrated circuit is presented and experimentally demonstrated.
Coherent Detection
In coherent detection, a strong local oscillator is used, mixing with the optical signal at the receiver and effectively amplifying the weak optical signal. Thus, compared to direct detection,
Advanced Fiber Sensing Leveraging Coherent Systems Technology
We show that coherent technology developed in the past decade for transmission over core optical networks can benefit to Distributed Fiber Sensing technology in various fields as sensitivity, sensing
